Sherry, Dawn Ann (Texas A&M University, 2007-04-25)I studied flock composition, distribution and foraging ecology of wintering wading birds along the Gulf of Mexico coast. I focused on geographic variability in wintering wading bird assemblages, the processes that structured ...
-
Pinkston, D. Randall (1978)The functional significance of mandibular papillae in feeding Roseate Spoonbills was studied. Feeding behavior of this species was investigated through observation both in the wild and under captive conditions. Spoonbills ...

Baker, Bruce William (Texas A&M University. Libraries, )The productivity and habitat use of Rio Grande turkeys (Meleagris gallopavo intermedia) was evaluated from May 1976 through November 1977 on the Welder Wildlife Refuge near Sinton, Texas. During the summers of 1976 and ...
-
Kinucan, Robert John (Texas A&M University. Libraries, 1987)Mechanisms of vegetation dynamics on a shortgrass (Hilaria belangeri) dominated semiarid Texas grassland were investigated. Study sites, which potentially support midgrass communities, were relatively homogeneous, open ...
-
Butcher, Jerrod Anthony (2009-05-15)Preservation of large tracts of habitat is often recommended for long-term population viability of area-sensitive species. Large tracts may not always be available. Smaller patches, though not able to contain a viable ...
-
Proudfoot, Glenn Arthur (Texas A&M University, 2006-08-16)Sequences of the cytochrome b gene and genotypes from 11 polymorphic microsatellite loci were used to assess phylogeographic variation in ferruginous pygmy-owls (Glaucidium brasilianum) from Arizona, Mexico, and Texas. ...
-
Taylor, Eric John (Texas A&M University. Libraries, 1993)I examined feather molt and bioenergetics of nonbreeding and failed-nesting Pacific Black Brant near Teshekpuk Lake, Alaska. Molt initiation primarily occurred during the first week in July but extended from 26 June through ...
-
Ballard, Bart M. (Texas A&M University. Libraries, 2001)Molt intensity, digestive tract morphology, diet, and carcass composition of northern pintails were investigated along the southern Texas Coast during winters of 1997-98 and 1998-99. Precipitation was 133% and 83% of the ...
-
Lee, Stephanie L. (Texas A&M University, 2007-04-25)North American grasslands and grassland birds have declined drastically due to habitat degradation by fire suppression (i.e., woody encroachment), fragmentation, and conversion to croplands. A better understanding is needed ...
-
Withers, Kim (Texas A&M University. Libraries, 1994)Shorebirds were censused and macrobenthic invertebrates sampled biweekly on two blue-green algal flats in the upper Laguna Madre from October 1991-October 1993. Twenty-two species of shorebirds were observed. Abundances ...
-
Markowitz, Timothy Michael (Texas A&M University, 2004-09-30)Social organization of dolphins in extensive societies has not been well studied. Off Kaikoura, New Zealand, thousands of dusky dolphins (Lagenorhynchus obscurus) gather, feeding nocturnally on deep scattering layer prey, ...
-
Butzler, Rachel Elizabeth (Texas A&M University, 2006-08-16)Understanding the salt marsh ecosystem in the Guadalupe Estuary is needed because wetlands in this system support the endangered whooping crane (Grus americana). The marsh plant research and monitoring described herein ...
-
LaFever, Kristin E. (2009-06-02)I investigated spatial and temporal winter behavior and behavioral responses of 5 territorial whooping crane families to human activities at Aransas National Wildlife Refuge during winters 2003-2004 and 2004-2005. Adult ...
-
Brown, Michael Lee (Texas A&M University. Libraries, 1993)This study evaluated the temporal genetics and energy dynamics of an intergrade largemouth bass population in Aquilla Lake, Hill County, Texas. Frequencies of alleles associated with Florida largemouth bass Micropterus ...
-
McCleery, Robert Alan (Texas A&M University, 2007-09-17)I studied the habitat selection, survival, and anti-predator behaviors of the fox squirrel (Siurus niger) across the urban-rural gradient in College Station, Texas. From two years of tracking the radio locations of 82 fox ...
-
Cummins, Tiffany (Texas A&M University, 2006-08-16)Over the last 50 to 150 years there has been widespread conversion of grassland to shrubland throughout the western United States. A major management concern on the Edwards Plateau is the encroachment of Ashe Juniper ...
-
Yantis, James Hugh (Texas A&M University, 2006-10-30)One strategy for conserving biodiversity is to select large-area preserves that complement each other so the maximum number of species is conserved. Estimates of biodiversity and complementarity are needed for optimum ...
-
Gil de Weir, Karine (Texas A&M University, 2006-08-16)The Whooping Crane (Grus americana) is among North AmericaÂs most charismatic species. Between 1938 and 2004, the population that migrates between Aransas National Wildlife Refuge (ANWR) and Wood Buffalo National Park ...
